Description

Anna�s Hummingbirds are among the most common hummingbirds along the Pacific Coast, yet they're anything but common in appearance. With their iridescent emerald feathers and sparkling rose-pink throats, they are more like flying jewelry than birds. Though no larger than a ping-pong ball and no heavier than a nickel, Anna�s Hummingbirds make a strong impression. In their thrilling courtship displays, males climb up to 130 feet into the air and then swoop to the ground with a curious burst of noise that they produce through their tail feathers.
Hummingbirds are New World birds that constitute the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5�13 cm (3�5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm bee hummingbird weighing less than a U.S. penny (2.5 g).

They are known as hummingbirds because of the humming sound created by their beating wings which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rates, typically around 50 times per second, allowing them also to fly at speeds exceeding 15 m/s (54 km/h; 34 mph) backwards.

Hummingbirds have the highest metabolism of any homeothermic animal. To conserve energy when food is scarce, and nightly when not foraging, they go into torpor, a state similar to hibernation, slowing metabolic rate to 1/15th of its normal rate.
